Weighing a property around Conway? Checking the Walsh County flood zone map reveals whether it sits in a FEMA flood zone, and no account is needed. In this county guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Walsh County ArcGIS parcel map, especially near Nash.
Getting started with the Walsh County flood zone map
For acreage around Voss, the official source is FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Rural land near Red River of the North with no street number can still be found: search the nearest road and click the spot.
Opening the official parcel viewer
Parcels around Red River of the North are published on the Walsh County ArcGIS parcel map, which opens without registering. If you only know roughly where the land is, pan along the nearest road until the lines appear, then click inside the one you want, and that holds around Grafton too. For a home near Nash, copy the parcel ID before closing the panel; each clerk in the county will want it.
Where the recorded documents are
For anything that matters, pull the recorded deed through the County Recorder; the viewer just points to it, and that holds around Voss too. For a parcel near Nash, use the instrument number from the tax record to skip a name search.
Limits of the parcel data
If you're looking near Hudson Bay, listed acreage is an estimate; only a licensed surveyor can set the real boundary on the ground. For a tract near Red River of the North, records update in batches, so a deed recorded last month can take weeks to appear.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Hudson Bay, so load it before you lose signal. A saved image of the lot near Fordville and its lines keeps working without signal.
Who handles what
Questions about value or the owner field for land near Red River of the North go to the Director of Tax Equalization, since that office keeps the assessment data. Questions about what you can build around Warsaw are for the local planning and health departments, and the answer depends on jurisdiction.
What the zone letters mean
Zone AE includes a base flood elevation (BFE), and an unnumbered A zone has none; builders around Auburn design to it. In and around Red River of the North, a low-risk label isn't a guarantee: according to FEMA, many claims come from moderate- and low-risk areas.
Sections, lots and bearings
North Dakota follows the Public Land Survey System, so deeds around Red River of the North reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Grafton vary in size. Keep the legal description for land near Fairdale when you talk to a surveyor.
Next door to Walsh County
Walsh County meets Marshall County, MN, Cavalier County, Grand Forks County, Nelson County, and Pembina County; every one of them runs a separate parcel map. A tract near the line by Ardoch can show up in two county records, so look at the neighboring map before you assume the acreage. For acreage around Hudson Bay, the Platbookmapper state page links every neighboring county map for North Dakota.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Walsh County ArcGIS parcel map too for the outline of the tract near Voss.
Lenders and permits
For land near Hudson Bay, an Elevation Certificate from a surveyor helps: it records the building's elevation against the base flood. Building or adding on near Red River of the North in a mapped zone usually means extra permit review; check with the county or town building office before you plan.
Water near Voss
Small streams around Hudson Bay aren't always studied in detail, so walk the land after rain. Wetlands near Hudson Bay can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Questions to ask before you buy
Ask the seller about past flood claims for the house near Warsaw; an insurance quote early avoids surprises.
Frequently asked
What if the flood map is wrong for my lot near Red River of the North?
Good question; you can ask FEMA for a LOMA if surveyed elevations show the building near Hudson Bay is above the BFE; a surveyor's elevation data supports it.
What is a base flood elevation near Hudson Bay?
In and around Grafton, the BFE is printed in AE zones on FEMA's map; local rules may require building above it.
Where can I see the Walsh County flood zone map for free?
For most people, FEMA's free map shows the zone for any spot near Ardoch National Wildlife Refuge; then confirm the parcel on the county viewer.
When is flood insurance required near Ardoch?
It depends, but lenders generally require it for buildings near Warsaw in a Special Flood Hazard Area when the loan is federally regulated or insured, in communities that take part in the NFIP.
What's a legal description around Conway?
For acreage around Auburn, deeds use lot and block, metes and bounds or survey descriptions; a surveyor can interpret it.
